DISTRICT OF COLUMBIA.

To all whom it may concern:

Be it known that I, JoHN PARK R LUQKETT, a citizen of the United States, residing at Baltimore, in the State of Maryland, have in vented a certain new and useful Automatic Faucet, of which the following. is a-specifica tion, reference beinghad therein to the accornanying drawin s.

. may be termed a self-closing faucet apwholly or partially within the T is invention re ates to automatic fancets, the object in view being to provide what plicable to any dispensing vessel or receptale, as a water-cooler,

the faucet-valve and the controlling and operating mechanism thereof being such that the valve is opened by'the pressure of a tumbler, cup, or other receptacle held in position to receive-the liquid as it is discharged from the faucet. Upon withdrawing, the receptacle the .valve instantly and automatically closes, and time cuts oil the flow of liqui through and from the faucet. 1

In automatic or self closing faucets as heretofore constructed the valve-operating device or devices have been located either body of the ,facuet, so that the liquid after. assihg the blers or receptacles in both hands and fill the description proceeds, t

valve came in contact with the va ve stem or 1 Valve-operating devices, rendering the same foul, and by reason of accumulation on and around the operating device ordevices impartingan unpalatable and obnoxious flavor to the coffee, tea, chocolate, milk,or.other liquid being dispensed. The chief aim of the present invention is to overcome this serious and fatal objection and to arrange the valveoperating device or devices wholly upon the exterior of the faucet-body, so that the liquid does not come in contact with an obstruction" of any kind after passing the faucet-valve. The dispensed liquid is therefore just as pure and wholesome as in the case of the present hand-operated faucet, while possesslng the advantage of enabling a waiter to carry tumthem without being compelled to use one hand to operate the controlling-valve.

With the above and other objects in view, the nature of which will ap ear more fully as r e invention con: sists in the novel construction, combination,

and arrangement of parts, as hereinafter fully described, illustrated, and claimed. In the accompanying drawings, Figure 1 is perspective view of the faucet, showing the manner of operating the same. Fig. 2 is a vertical longitudinal section through the same,'illustrating in detail the valve and the operating device therefor. Fig. 3 is a bottom'plan view of the valve-operating lever andVpacking-nut. Fig. l is a detail vertical section through the same, showing also a portion of the valve-stem.

I'Like reference-numerals denote like parts in all the figures of the drawings. 7

Referring to the drawings, 1 designates a faucet-body which has the general appearance of faucets now in use, being rovided with an enlargement 2, in which is ormed a valve-seat 3, said valve-seat being arranged end ofthe faucet and preferably in the horizontal portion of the faucet-body as it appears when connected with a vessel or recepprovided with a boss or pendent extension 5,

H1 which is received the body ;6 of the faucet -controlling valve 7, which is preferably conical to correspond and fit snugly the valve-seat 3, as clearly shown in Fig. 2. The body 6 extends downward and outward through the extension 5 and also through a packing-nut 8, the up er por tion of which I is internally screw-t eaded and encircles a cmrespondinglythreaded lower portion of the extension 5. The body 10 bears, said springencircling the lower reduced ing its wer end seated against a washer 11, preferably formed of metal, while below the Washer 11 is arranged a packing-washer 12,

which being compressed between the washer 11 and the outer or lower wall of the nut 8 packing-nut and the valve-stem, venting escape of liquid. p

In order to operate the valve, I employ a lever 13; which is centrally recessed, as shown at 14, to receive the lower reduced extremity of the valve-stem, to which it is connected by means of a pivot 15. On its upper side 6 terminates at 9 in an annular shoulder, against-which the upperend of a coiled spring forms a close liquid-tight joint between the thereby preat a considerable distance from thedischarge tacle, as shown at 4. The faucet-body is also elongated cylindrical portion or stem of the valve and hav- I I servo by coming in contact with the lower surface of the not 8 to priment the opposite and of the lover from dropping down too tar.

The forward end of the lever is recessed, as

shown at 18 to receive a pad or cushion 19, preferably of rubber or analogous material, and also by preference having its lower surface scored o1- sei're'ted, as shown at 20, to en- 'oblo the upper edge of a timxblei' or glass or other recap scie'to obtain a betterhold there- "on and also to prevent the bi'eeking or chipping the GCif 'G of said glass or tumbler. it will now 0 understood that by placing e glass or tumbler or other ieceptzicle beneath the faucet and exerting en upwiii'd pressure against the pad or cushion 19 in the manner illustrated in Fig'. 1 the lever 13 is rocked on the pivot 15, causing the cam projection 16 cpembe against the packing-nut, with the result that the velvdstem 6, thrown down- (Pd. t shy unsouting the valve and 31-15% iquid to escape. Vi'hoi'i the tumbler 1r gle filled to the desired exlacnt, it islowcred, whereupon the spring 10 acts to elevate the stem 6, thereby closing the valve 7 and culling; 05 the flow of ligiiid. The faucet is thus automatic and sclf-closing in operation and is opened merely by the pressure of a rece'ptecle held beneath ihe faucet, enabhn a waits: oi oiher person. to use both hands or holding such receptacles. hie ol' the. chief advantages of the present inventivim. resides in the fact that the valve is located at :1V con sidemblc distance from the discharge end of nozzle and the mi-lvo-opembino; devices are located. Wholly upon ihe exterior of the v i'r iucet, thus doing ova-1y with. any inside mechanism about which ihe col-lee, tee, milk, L161 liquid can eceunmlote and become 'ovidcd with it com brojection l aisjsee foul, which would naturally result in rendiing on alatable any liquid subsequently drawn tom the cooler or other recegimcle to which the faucet is ettgched.

The joint between the velve oody (i and the boss 5 is referzibly ground to insure ii liquid-tight ht, which prevents the liquid from coming in contact with the valve-seating spring, packing-nut, and other parts of th valve mechanism.

Having thus described the invention, whet is claimed as new is- The OOlIlblIliLtlOIl of o faucet-body provided with a tubular boss depending from the lower side thereof at a point remote from the discharge end thereof, a vertically-movable valve working in said boss, 2. pockifig-nut having a detachable connection with the bottom of said boss, a valve-actuating springincloced Within and retained by said nut, end :1- i101 zontally-disposed valve-operating lever si ranged beneath the fauoet-bcdy mild pivotally connected to and carried by the lower end of the VfLlVS-Gtfilll and having its forward and located nea'r the discharge end of the faucet.

The combination of e feuceobody, e valve therein having a stem extendingdownword through the faucet-body, an extericrlyrocved nut detachebly connected with the toucet-body and surrounding the stem, and a valve-operating lever loceted beneath the faucet-body and pivotally connected it one end to the valve-stem, said lover having one or more projections wbich'eiigege the grooved.
